so i have an 04 gt. have a mach 1 kit on it i believe with the 40 mm pistons. well the car pulls so i have an issue anyways. well i just got a new set of actally cobra calipers powdercoated red nice set. but i think they are a 98 caliper. the back side of the piston has the humps. its not flat like the 99-up ones. so i really lioke the cobra calipers and they look awesome and match the car. so is the 38 mm going make a huge differance than the current 40 mm i have now. the car is street driven so should i jsut use the nice looking calipers? any input is appreciated thanks
